1. Antioxidant & Anti-inflammatory Core
• Alpha Lipoic Acid (ALA) – 300–600 mg/day
Universal antioxidant; regenerates glutathione and vitamins C/E; crosses the BBB.
→ Reduces oxidative stress in dopaminergic terminals.
• N-Acetyl Cysteine (NAC) – 600–1200 mg, 2× daily
Precursor to glutathione; reduces excitotoxicity; blunts MA-induced microglial activation.
→ Proven to reduce amphetamine-induced neuronal apoptosis in animal models.
• Vitamin C – 500–1000 mg, 2× daily
Reduces oxidative stress and catecholamine auto-oxidation; supports dopamine synthesis.
→ Co-administer with zinc for full antioxidant cycle closure.
• Vitamin E (d-α tocopherol) – 200–400 IU/day
Lipid-phase antioxidant that protects neuronal membranes.
→ Synergistic with ALA and Vitamin C.
• Curcumin / Turmeric Extract (≥95% curcuminoids) – 500 mg/day
Anti-inflammatory via NF-κB inhibition and microglial suppression.
→ Enhances BDNF and reduces MA neuroinflammation markers.
---
2. Mitochondrial & Energy Support
• Acetyl-L-Carnitine (ALCAR) – 500–1000 mg/day
Improves mitochondrial ATP output and synaptic repair.
→ Helps restore dopaminergic energy metabolism post-MA.
• Coenzyme Q10 (Ubiquinol) – 100–200 mg/day
Mitochondrial electron transport cofactor; synergistic with ALCAR.
→ Reduces MA-induced lipid peroxidation and protects striatal mitochondria.
• Creatine Monohydrate – 3–5 g/day
Stabilizes ATP levels and phosphocreatine buffer during neural stress.
→ Shown to reduce dopaminergic neuron loss in oxidative models.
---
3. Neurotransmitter & Synaptic Recovery
• L-Tyrosine – 500–1500 mg/day
Precursor to dopamine, norepinephrine, and epinephrine.
→ Replenishes catecholamines post-MA use.
• DL-Phenylalanine (DLPA) – 250–500 mg/day
D-enantiomer inhibits enkephalinase; L-enantiomer → dopamine precursor.
→ Supports mood and catecholamine balance.
• Citicoline (CDP-Choline) – 250–500 mg/day
Boosts membrane phospholipids and acetylcholine; protects dopaminergic terminals.
→ Enhances synaptic plasticity after stimulant exposure.
• SAM-e – 200–400 mg/day
Methyl donor for dopamine metabolism and neuronal repair.
→ Supports monoamine turnover; synergistic with B12 + folate.
---
4. Neuroinflammation Modulators
• Omega-3 Fatty Acids (EPA/DHA) – 1–2 g combined/day
Anti-inflammatory; regulates microglia and synaptic fluidity.
→ Restores neuroplasticity and suppresses neuroinflammatory cytokines.
• Palmitoylethanolamide (PEA) – 300–600 mg/day
Endogenous fatty amide that downregulates mast cell and glial activation.
→ Strong neuroinflammation modulator with minimal side effects.
• Resveratrol – 200–400 mg/day
Activates SIRT1 and suppresses microglial NF-κB.
→ Reduces MA-induced neuronal apoptosis in animal models.
---
5. Sleep & Serotonin System Repair
• 5-HTP – 50–100 mg before bed
Serotonin precursor; supports post-MA serotonergic recovery.
→ Use cautiously; avoid within 12 hours of MA to prevent serotonin syndrome.
• Melatonin – 1–5 mg nightly
Strong antioxidant and circadian regulator.
→ Reverses MA-induced oxidative stress and sleep disruption.
• Magnesium (glycinate or citrate) – 200–400 mg/day
NMDA receptor modulator; prevents excitotoxicity.
→ Restores calm, reduces glutamate overactivity.
---
6. Adjuncts for Vascular & Systemic Protection
• Vitamin D3 – 2000–5000 IU/day
Anti-inflammatory, supports dopaminergic neurogenesis.
→ Correlates inversely with stimulant-induced neurotoxicity.
• Zinc – 15–25 mg/day
Cofactor for dopamine synthesis and antioxidant enzymes.
→ Prevents catecholamine auto-oxidation damage.
• Iron (if deficient only)
Required for tyrosine hydroxylase (dopamine synthesis).
→ Avoid excess; iron overload worsens oxidative stress.

7. Stacking Summary
Morning stack:
ALA + NAC + ALCAR + CoQ10 + Tyrosine + Citicoline + Vitamin C + D3 + Omega-3
Evening stack:
Curcumin + PEA + Magnesium + Vitamin E + Resveratrol + Melatonin + 5-HTP
